WASHINGTON (NewsNation Now) — The United Arab Emirates and Bahrain signed agreements on Tuesday for normalizing relations with Israel, becoming the latest Arab states to break a longstanding taboo in a strategic realignment of Middle Eastern countries against Iran.

President Donald Trump presided over the signing of diplomatic deals between Israel and two Gulf Arab nations.

Hundreds of people massed on the South Lawn to witness the signing. The bilateral agreements formalize the normalization of the Jewish state’s already thawing relations with the two Arab nations in line with their common opposition to Iran and its aggression in the region.

“We’re here this afternoon to change the course of history,” Trump said from a balcony overlooking the South Lawn. “After decades of division and conflict, we mark the dawn of a new Middle East.”

In front of a crowd, Prime Minister Benjamin Netanyahu signed accords with Emirati Foreign Minister Sheikh Abdullah bin Zayed al-Nahyan and Bahrain’s Foreign Minister Abdullatif Al Zayani.

The U.S.-brokered ceremony capped a dramatic month when first the UAE and then Bahrain agreed to reverse decades of ill will without a resolution of Israel’s decades-old dispute with the Palestinians.

The deals, denounced by the Palestinians, make them the third and fourth Arab states to take such steps to normalize ties since Israel signed peace treaties with Egypt in 1979 and Jordan in 1994.

Meeting Netanyahu earlier in the Oval Office, Trump said, “We’ll have at least five or six countries coming along very quickly” to forge their own accords with Israel. But he did not name any of the nations involved in such talks.

The agreements won’t end active wars but will rather formalize the normalization of the Jewish state’s already warming relations with the two countries. And, while not addressing the longstanding Israeli-Palestinian conflict, they may pave the way for a broader Arab-Israeli rapprochement after decades of enmity, a pair of wars and only two previous peace deals.

During the ceremony, Emirati Foreign Minister Sheikh Abdullah bin Zayed Al Nahyan, the brother of Abu Dhabi’s powerful crown prince, thanked Israel for “halting the annexation of Palestinian territories,” although Israeli Prime Minister Benjamin Netanyahu has insisted that Israel has only temporarily suspended its plans to annex West Bank settlements.

“Today, we are already witnessing a change in the heart of the Middle East — a change that will send hope around the world,” al-Nahyan said.

In addition to the bilateral agreements signed by Israel, the UAE and Bahrain, all three are signing a document dubbed the “Abraham Accords” after the patriarch of the world’s three major monotheistic religions.

“This day is a pivot of history,” Netanyahu said. “It heralds a new dawn of peace.”

“Despite the many challenges and hardships that we all face — despite all that, let us pause a moment to appreciate this remarkable day.”

The Palestinians have not embraced the U.S. vision. Palestinian activists held small demonstrations Tuesday inthe West Bank and in Gaza, where they trampled and set fire to pictures of Trump, Netanyahu and the leaders of the UAE and Bahrain.

Even in Israel, where the accords have received widespread acclaim, there is concern they might result in U.S. sales of sophisticated weaponry to the UAE and Bahrain, thus potentially upsetting Israel’s qualitative military edge in the region.

Trump said he is OK with selling military aircraft to the UAE. House Speaker Nancy Pelosi also welcomed the agreements but said she wants to learn details, specifically what the Trump administration has told the UAE about buying American-made F-35 aircraft and about Israel agreeing to freeze efforts to annex portions of the West Bank.

Bahrani Foreign Minister Abdullatif al-Zayani said Bahrain would stand with the Palestinians. “Today is a truly historic occasion,” he said. “A moment for hope and opportunity.”

And while the UAE and Bahrain have a history of suppressing dissent and critical public opinion, there have been indications that the agreements are not nearly as popular or well-received as in Israel. Neither country sent its head of state or government to sign the deals with Netanyahu.

The ceremony follows months of intricate diplomacy headed by Jared Kushner, Trump’s son-in-law and senior adviser, and the president’s envoy for international negotiations, Avi Berkowitz. On Aug. 13, the Israel-UAE deal was announced. That was followed by the first direct commercial flight between the countries, and then the Sept. 11 announcement of the Bahrain-Israel agreement.
